This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.
Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.
A number of methods in React are assumed to be "pure".
On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.
To use media keys on the Ducky One 2 Skyline, you must record a macro to bind the media function to a hotkey combination, i.e. Fn
plus some key.
Important: In the instructions below, "Press X+Y+Z
" means press and hold key X
, press and hold key Y
, press and hold key Z
in that order, and then release all three.
As an example, to bind Fn+PgUp
to the play/pause media function:
#!/bin/bash | |
# | |
# NOTE: specify the absolutepath to the directory to use when | |
# loading a plugin. '~' expansion is supported. | |
# | |
chunkc core::plugin_dir /usr/local/opt/chunkwm/share/chunkwm/plugins | |
# |
console.log(1); | |
(_ => console.log(2))(); | |
eval('console.log(3);'); | |
console.log.call(null, 4); | |
console.log.apply(null, [5]); | |
new Function('console.log(6)')(); | |
Reflect.apply(console.log, null, [7]) | |
Reflect.construct(function(){console.log(8)}, []); | |
Function.prototype.apply.call(console.log, null, [9]); | |
Function.prototype.call.call(console.log, null, 10); |

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
